Probably what you mentioned earlier about flow into pipes
--------------------------------------
I found and then lost a webpage that showed the flow into pipes.
Thought I could find it again and share....but naught.
Essentially it was establishing a coefficient rating for different pipe entrances.
Some very real figures for us spudders.
--------------------------------------

I would be interested too if you don't mind sending it to me as well bnoji.

I remember reading about flow in the deep well drilling....basically, sharp edges are the absolute worst for flow.
A feature I avoided with the WaterDawgÃ¢â€žÂ¢ by bullnosing every sharp edge.

barrel sealing piston valve.how much pressure you are going to use:?:.
burstdisc open fastest, but it is not safe to use and you have to change the disck after every shot:x...
if your going to make your first valve make barrel sealing or coaxial piston valve:D
